We often talk about the "energy-water nexus", recognizing that pumping, cleaning and treating water is a significant contributor to energy use. In 2015, water conservation programs in California reduced water use by more than 20%, but the energy savings and subsequent GHG reductions weren't quantified, until now.
Modeling Suntubes to Design for Daylight
The benefits of natural light within the built environment have now been researched, written about and accepted as a fundamental design characteristic in successful architecture. Creating a connection to the outdoors provides the stimulation required to regulate our circadian rhythms, which can result in improved comfort and productivity. In addition, increasing natural daylight in our homes and work environments decreases the demand for electric lighting and therefore, electricity consumption.
